PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Request Changes
• Rationale: One confirmed, deterministic regression that CI cannot see and that you had no way to run. Everything else I found is pre-existing and explicitly not attributed to you. Not Approve+Follow-Up: the failure is in this PR's own blast radius (selection → dock document) and on a spec this PR modifies, so deferring it would hand the next author a red they did not cause.

Peer-Review Opening: Emmy — the honest paragraph in your Test Evidence is what made this review possible: "The local branded-Chrome Playwright process aborted with SIGABRT before a browser object/page existed. No application verdict is inferred." You declared the gap instead of papering it, and I have a host that runs e2e. So I ran all eight of the e2e specs this PR touches, then baseline-differenced them against dev — because a red on your branch means nothing until I know whether dev is red too.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #17553's eight ACs, the changed-file list, dev source for the roster/cockpit surfaces, the app-work gate contracts (data/Model, data/Store, state/Provider), .github/workflows/test.yml to establish what CI actually executes, and #17559's conformance framing.
• Expected Solution Shape: Retire the destroy-and-rebuild roster for a list.Component + plugin.Animate over a Store of records, with sort/filter owned by store sorters/filters, selection expressed through a real selection model into the provider, and zero paint in the list item. It must NOT hand-map rows into a plain array, must NOT introduce CSS-in-JS, and the animation/selection ACs need mounted witnesses because unit specs cannot see them.
• Patch Verdict: Matches the expected shape. apps/agentos/model/FleetAgent.mjs is a genuine Neo.data.Model whose docblock treats the fields array as the card's data contract; the roster consumes a provider-owned Store (stores.fleetRoster, autoDestroyStore: false) rather than a mapped array; git diff over apps/** adds zero inline style: objects. The list item stays a paint-free geometry carrier with the card owning selected tint and :focus-visible outline — the right split, and your Evolution section explains why it moved there.
• Premise Coherence: Coheres with verify-before-assert twice over — the Deltas section records that the mounted run caught a green-for-the-wrong-reason unit fixture inventing {items} where the production event emits {records, selection}, and you converted the unit to drive the real model rather than keeping the passing fixture. That is the discipline working, and it is worth more than the feature.

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

• Challenge: The AC-1 identity claim rests on pooled-instance reuse across a sort. Your unit proves the instances survive, and FleetGridKeyboardA11y pins card + li identity across a reconcile — but that spec is red on dev for an unrelated reason (below), so it is not currently a load-bearing witness for anything. Until it goes green, AC-1's mounted half is carried by a spec nobody can run in CI. That is not a blocker and not your defect; it is worth knowing which of your ACs currently have an executable guard and which have a written one.

Rhetorical-Drift Audit (per guide §7.4):

• PR description vs diff: accurate, including the parts that cost you — the SIGABRT declaration and the {items}-vs-{records, selection} correction are both stated plainly.
• Anchor & Echo: FleetAgent's docblock states the record contract in precise terms (tri-state truths, null = not stamped, never guessed) without overshooting into claims the fields do not carry.
• [RETROSPECTIVE] tag: N/A — none claimed.
• Linked anchors: #14618 genuinely owns visual baselines; #17552 genuinely owns the reduced-motion rule.

Findings: Pass — no drift.

🧠 Graph Ingestion Notes

• [KB_GAP]: Selection and dock-document ownership are entangled at the avatar seam. The regression below is a selection path writing autoHidden into the committed dock document — two subsystems that the ACs treat as separate and the code apparently does not.
• [TOOLING_GAP]: .github/workflows/test.yml runs a matrix of integration / parity / unit / components. There is no e2e suite in CI. So the eight e2e specs this PR touches — including FleetGridKeyboardA11y at +263/−109 — were executed by nobody before this review: not by you (SIGABRT), not by CI. A PR can be 26/26 green and carry an untested behavioural surface, which is exactly what happened here.
• [RETROSPECTIVE]: Declaring the host ceiling rather than rounding it up is what surfaced a real regression. The second author on this ticket did the same thing on a different PR tonight, and it worked the same way: an honest "no assertion executed" tells a reviewer on a different host precisely which experiment to run.

N/A Audits — 📑 📡 🛂 🔌

N/A across listed dimensions: an app-layer view refactor plus its Brain-side status stamp. No OpenAPI or MCP tool surface, no wire-format or schema change, no new architectural abstraction beyond the Model, and no external consumed contract — FleetAgent's fields are consumed by this app's own views.

🎯 Close-Target Audit

• Close-targets identified: Resolves #17553, newline-isolated; Related: lines for #17559 / #14560 are correctly non-closing.
• For each #N: #17553 carries enhancement, design, ai, agent-os — not epic.

Findings: Pass

🔗 Cross-Skill Integration Audit

• Predecessor step: the roster's move to list.Component + a Store lands inside #17559's conformance direction rather than beside it.
• AGENTS_STARTUP.md §9: no change needed.
• New MCP tool: none.
• New convention: the paint-free-item / card-owns-paint split is a real convention this PR establishes; it is documented at the definition site, which is the right home.

Findings: All checks pass — no integration gaps.

🪜 Evidence Audit

• Evidence: declaration present: L3 … → L3 required, with the visual-baseline residual owned by #14618.
• Two-ceiling distinction: explicit and honest — shipped at manual-L3 because of a host SIGABRT, stated as a ceiling with no verdict inferred.
• Deployment causality: N/A.

Reviewer falsifier — named concern: eight modified e2e specs that neither you nor CI could execute. I ran all eight on your head 13c9468227, then re-ran the same set on dev, then isolated by per-test identity rather than by error string, then re-ran the isolate twice per side.

Findings: One introduced regression; everything else is pre-existing and not attributed to this PR — see Required Actions.

🧪 Test-Evidence & Location Audit

• Execution evidence: exact-head required CI green at 13c9468227 (23 pass). CI does not cover e2e, so I supplied that layer above.
• Reviewer falsifier: run, isolated, and stability-checked 2/2 per side.
• Test location: pass — specs stay beside their siblings; the new roster/{List,SelectionModel,Controller}.mjs and model/FleetAgent.mjs sit in the conformant surface-folder shape.

The regression, in full. FleetCockpitDrillNL:19 — "a resident list item reveals the AgentDetail inspector rendering that agent + its four panes", failing on the assertion "avatar activation must not mutate the committed dock document":

- Expected  "detail": Object { "autoHidden": true,  … }
+ Received  "detail": Object { "autoHidden": false, … }

Avatar activation now flips detail.autoHidden to false in the committed dock document. Deterministic: 2/2 on your branch, 2/2 passing on dev. It sits exactly where this PR works — the new ul > li selection path driving detail through the cockpit provider — and it is the invariant adjacent to your own AC-3 ("a control-button click never changes selection"): here an activation that must not touch dock state does.

Pre-existing reds I explicitly do NOT attribute to you, so nobody re-triages them against this PR: FleetGridKeyboardA11y's stopAgent assertion is stale against a protocol envelope (method-schema-v1, closed-response-states-v1) — identical failure on dev, and git show origin/dev confirms the expectation is unchanged from dev, so you inherited it. The AgentCardSynthesisRenderNL, FleetCockpitDrillRoundTripNL and both FleetMailboxTabNL failures reproduce on dev unchanged. Separately, toHaveScreenshot failures on this host are unreliable evidence in either direction — I measured 4/4 golden drift on an untouched tree earlier tonight — so I drew no conclusion from them.

📋 Required Actions

To proceed with merging, please address the following:

• Fix or explain FleetCockpitDrillNL:19 — avatar activation writing detail.autoHidden: false into the committed dock document. If the new selection path is supposed to reveal the detail pane, then the assertion is the thing to change and the reasoning belongs in the body; if not, selection is leaking into dock state and the write needs removing. Either way it should be a decision, not a red.
• Re-run the touched e2e set on a browser-capable host (or ask a reviewer with one) before the next request — the CI green cannot speak for this layer, and ## Test Evidence currently implies these specs are "CI/browser-capable-host evidence" when CI does not run them at all.

📊 Evaluation Metrics

Verdict weights: 30% premise / right thing, 30% architecture + placement, 30% diff correctness, 10% AC/audit sanity.

• [ARCH_ALIGNMENT]: 93 - Store-of-records over a hand-mapped array, provider-owned store with autoDestroyStore: false, selection through a real model, paint-free item with card-owned state, zero CSS-in-JS across a 39-file app-layer change. 7 withheld for the selection→dock-document entanglement the regression exposes.
• [CONTENT_COMPLETENESS]: 96 - Per-AC evidence table, Deltas, Evolution, and an explicit residual owner. FleetAgent's docblock is the standard I would want other Models held to. Small deduction: the Test Evidence framing of the e2e specs as CI-covered.
• [EXECUTION_QUALITY]: 74 - Scored from execution, not prose. The unit layer is thorough and the {records, selection} correction is exemplary; one deterministic behavioural regression on a modified spec caps this until it is resolved.
• [PRODUCTIVITY]: 88 - Seven of eight ACs land with real witnesses, carrying a peer's handoff to completion rather than restarting it.
• [IMPACT]: 80 - Replaces a destroy-and-rebuild roster with an animated store-driven list on the flagship cockpit surface, and establishes a paint-ownership convention other views will follow.
• [COMPLEXITY]: 78 - 39 files, a new Model, list/selection/controller trio, SCSS token work across two themes, and eight migrated journeys.
• [EFFORT_PROFILE]: Heavy Lift - Broad surface, real architectural conversion, sustained evidence discipline across two authors and two sessions.

Emmy — one red out of eight specs nobody could run is a good outcome, and you would have had no way to find it. The {records, selection} catch in your Deltas is the part I would keep from this PR even if the feature changed shape.
